Ultrasonic welding
Ultrasonic welding takes advantage of the physical
fact of the friction energy of moving boundary surfaces.
When two preforms are pressed together at their connecting surfaces and
excited using high-frequency ultrasonics, the surfaces
of the two parts to be joined generate so much energy that their
connecting surfaces fuse together. This functions with
both: metal parts and plastic parts. The ultrasonic
energy is fed via a so-called sonotrode to the parts
to be joined. The sonotrode amplifies the ultrasonics
generated by the piezo composite transducer. The piezo
composite transducer consists of two or more piezoceramic
perforated disks which are mechanically pre-stressed using
two metallic end pieces. Ultrasonic welding has established
itself in industry as a very fast, cost-effective and
reliable joining technology.
